Emily Meineke, assistant professor of urban landscape entomology, UC Davis Department of Entomology and Nematology, helped launch the project in 2017 when she was a postdoctoral fellow at the Harvard University Herbaria.
The exhibit in Cambridge, Mass., is “an immersive multidisciplinary experience that marries art and science through a modern artistic interpretation of Henry David Thoreau's preserved plants,” said Bethany Carland-Adams, a public relations specialist with Harvard Museums of Science and Culture (HMSC).
Henry David Thoreau (1817-1862), naturalist, author and philosopher and a 1837 graduate of Harvard University, is best known for his book Walden. Removing himself from social life, he settled into a cabin by Walden Pond, Concord, Mass., from July 1845 to September 1847 to immerse himself in nature.
The 648 plant specimens that Thoreau donated to the museum form the foundation of the exhibit. "He was prolific in his practice of collecting botanical samples and plants are important indicators of how our world is responding to climate change," Carland-Adams said in a press release.
Meineke, who joined the UC Davis faculty in 2020, served as a postdoctoral fellow at Harvard University Herbaria from 2016 to 2019, including a National Science Foundation-sponsored fellowship there in 2017. She holds a doctorate in entomology from North Carolina State University (2016), Raleigh, where she wrote her dissertation on “Understanding the Consequences of Urban Warming for Street Trees and Their Pests.”
“Ultimately, we landed on using visual media and portraits to highlight the decline of local plants," Meineke said. "Those art works are now central to the exhibit, as are Thoreau's actual specimens provided by Harvard and descriptions of the discoveries made possible by his work as a naturalist.”
The exhibit includes Meineke's work on insect herbivore-plant interactions over the period of recent climate change as one type of research made possible by Thoreau's plant collections.
“The digitization of the specimens, and others in the Herbaria collection, are now allowing broader access to scholars and citizen scientists, in turn welcoming new domains of scholarship,” Carland-Adams noted. "The exhibition invites visitors to experience emotionally resonant connections to the profound loss of natural diversity caused by human-induced climate change. The exhibition urges us to ask, 'What do Thoreau's findings tell us about what plants are winning, and what plants are losing, in the face of climate change today?'"
Charles Davis, curator of vascular plants at Harvard University Herbaria, teamed with Marsha Gordon, a North Carolina State University professor, and Meineke to frame plans for the exhibit, collaborating with artists Leah Sobsey and Robin Vuchnich, both university faculty members, to shape the vision.
Vuchnich, an assistant professor at North Carolina State University, leveraged the digitized specimens to craft an immersive experience in the gallery theater. It includes animations of the herbarium images and soundscapes recorded at Walden Pond.
Sobsey, an associate professor of photography and director of the Gatewood Gallery at the University of North Carolina, Greensboro, focused on cyanotype, a 19th-century photographic process that relies on UV light to create a distinctive Prussian blue tone. Sobsey utilized all 648 digitized Thoreau specimens, and created a wallpaper comprised of original cyanotypes and digital imagery, relating a story of the survival and decline of plant specimens.
In the news release, HMSC executive director Brenda Tindal emphasized the significance of Thoreau's observations and his indelible impact on society..."Thoreau's clarion call compels us to intentionally lean into our surroundings and learn from nature—and by extension, the global community to which we all belong.”
Visitors will gain "a deeper understanding of how different plant species respond to environmental factors, within and between species," Carland-Adams shared. "For instance, some plants are sensitive to temperature, while others show less or no sensitivity. This type of data drives the exhibition's animations and directly impacts our daily lives in the context of agriculture and food production."
The Thoreau exhibit may also become a traveling exhibit.
The HMSC mission "is to foster curiosity and a spirit of discovery in visitors of all ages by enhancing public understanding of and appreciation for the natural world, science, and human cultures," according to its website. "HMSC works in concert with Harvard faculty, museum curators, and students, as well as with members of the extended Harvard community, to provide interdisciplinary exhibitions, events and lectures, and educational programs for students, teachers, and the public. HMSC draws primarily upon the extensive collections of the member museums and the research of their faculty and curators."
